A spa booking can become considerably better value when the saving is fixed rather than buried in a complicated package. OASIS Spa is offering two straightforward benefits for eligible KTC Mastercard and KTC PROUD Mastercard cardmembers until 31 December 2026.
Spend at least THB 3,000 on an eligible spa package and the card benefit removes THB 1,000 from the bill. For other spa services, the alternative benefit is a 10% discount. There is no advance promotion registration, although booking ahead with the spa remains wise if you have a preferred treatment time.
Choose the right saving
The THB 1,000 reduction is the stronger headline offer, but it only applies when the package total reaches THB 3,000. The 10% route is more flexible for individual services. On a THB 2,500 service, for example, 10% would be THB 250, while a qualifying THB 3,000 package would receive the fixed THB 1,000 reduction.
Do not choose a longer or more expensive treatment purely to cross the threshold. Decide what experience you want first, then compare the eligible price under both routes. Ask whether the quoted package price includes all charges and confirm which card benefit will be applied before the treatment begins.
How to use the offer
- Contact OASIS Spa and choose your location, treatment and time.
- Say that you intend to use the KTC Mastercard promotion.
- Confirm whether the fixed THB 1,000 package saving or 10% service discount applies.
- Pay with an eligible KTC Mastercard or KTC PROUD Mastercard and check the final bill.
The offer cannot be combined with other promotions or discounts unless the spa confirms otherwise. Because treatment availability and package menus can differ by branch, the safest approach is to have the team confirm the exact service name, duration and final payable amount when you book.
Good occasions to book
A fixed package saving is useful for a birthday treatment, a restorative afternoon during a Thailand trip or a shared wellness day. It can also suit residents who already know which OASIS treatment they prefer. If you are buying a gift or voucher, ask whether that purchase qualifies, since card promotions often distinguish between treatment bookings and stored-value products.

Dates and card eligibility
The campaign is scheduled from 1 April through 31 December 2026. It is limited to eligible KTC Mastercard products, including KTC PROUD Mastercard. Check the card network and product name before arranging the visit, especially if you hold several KTC cards.
Make the booking directly with the spa and reconfirm the promotion on the day. A calm arrival is part of the experience, and a two-minute price check beforehand is much more pleasant than sorting out an ineligible service at reception.
